Q.1 Overview
Figure Q-1. CDM-570A/570AL Advanced Satellite Modem
The CDM-570A/570AL Advanced Satellite Modem (Figure Q-1) provides a “Dedicated
Management Port” function. When you use a single Ethernet port for both modem management
(referred to as monitor and control, or M&C) and user data traffic, this not only causes many
security issues, it also creates difficulties when converging two networks to a single port.
Dedicated Management Port operation mitigates these issues.
Dedicated Management Port is available in the Managed Switch, Router Point-to-Point, and
Router Point-to-Multipoint working modes when the optional High-Performance Packet Processor
is installed and enabled. With Dedicated Management Port, the CDM-570A/570AL uses the
modem’s onboard ‘10/100 Ethernet | M&C 100’ port (Figure Q-1, Item 1) for M&C access, and
the Packet Processor ‘10/100 Ethernet | Traffic 100’ port (Figure Q-1, Item 2) for Ethernet data
traffic. This allows you to separate the M&C and traffic networks, and restricts user access for
modem M&C to the “dedicated” port.
